HarperCollins has announced that it will, for the very first time, publish The Fall of Gondolin on 30 August this year.
Edited by Christopher Tolkien and illustrated by Alan Lee, The Fall of Gondolin will follow the same format as Beren and Lúthien published last year, separating out the story so that it stands alone while showing how the narrative evolved over the years. This is the first time the tale of the Fall of Gondolin will be published as a standalone edition, collecting all versions of the story together.

Alas, I've never put my hands on The History of Middle-earth, but Of Tuor and the Fall of Gondolin is my favourite chapter of Unfinished Tales, so I'm looking forward to reading other versions of the story
